Mādhavānanda: "The vaiśyas are meant for producing agricultural products, trading them and distributing them. And the working class, or śūdras, are those who haven't the intelligence of the brāhmaṇas or the kṣatriyas or the vaiśyas, and therefore they are meant to help these higher classes by bodily labor. In this way, there is full cooperation and spiritual advancement amongst all the different orders of society. And when there is no such cooperation, the members of society will fall down. That is the present position..."
Prabhupāda: Yes. That is everywhere. Even in, in our society, Kṛṣṇa conscious society, if there is no mutual cooperation, then it will fall down immediately. So as Rūpa Gosvāmī advises, the first thing is enthusiasm, utsāhān. Utsāhān dhairyāt tat-tat-karma-pravartanāt... (aside:) Why Śyāmasundara is not here? Tat-tat-karma-pravartanāt, sato vṛtteḥ sādhu-saṅga ṣaḍbhir bhaktiḥ prasidhyati. If you want actually to make progress in our devotional life, the utsāhān, enthusiasm, is the first thing. If you are lacking enthusiasm, then you should rest, instead of making too much agitation within the mind. The... If you cannot find out... Some, something has dropped in the water, in the river, you cannot see the things dropped within the water by agitating the water. Just stand still for sometimes. As soon as the water is settled up, you'll see the things as they are. So as soon as our enthusiasm is agitated, it is better to sit down in any temple suitable and chant Hare Kṛṣṇa. There is no question of being disappointed. After all, we commit so many mistakes. That is human nature. To err is human. That is not fault. But try to rectify with cool head. That is required. So similarly, there are different classes of men in the society: brāhmaṇa, kṣatriya, vaiśya, śūdra. They should cooperate for the common cause. They do not know the common cause. The common cause is Kṛṣṇa. For Kṛṣṇa's service, we should submit to the immediate officer or commander. Just like soldiers. Soldiers, there is no question of discrimination. Whatever is ordered by the commander, immediately done. Go on.
